4x4 Cobra front brakes

So I am working to eventually go to front and rear cobra brakes and I am wondering if the caliper mounts on the 2x4 and 4x4 are the same on both spindles? Reason being is I want to get the dimensions for the 2x4 caliper adapter and machine my own based off of those measurments so I get it lined up right. I know 2 brothers in Oregon are working on this too so share what you have found.

Discuss!

The top is offset more than the bottom. The calipers center to center distance is smaller than the ranger, so the top mount is offset more. I think if i had teh time and a machine shop, i could easily fab a bracket up.

The rotor slid on perfectly fine like it was meant to be!

On to PICS!





Bottom bolt hole:




Top bolt hole:






There is about a .75inch distance between the caliper and the face of the spindle where it bolts to:



I believe it to be totally doable. You might have to clock the caliper, so you can properly bolt the caliper to the spacer then to the spindle. Also, i think the hat of the cobra rotors are thicker because it seems that not much wheel stud is sticking out for you to thread onto.

Oh, and i'm pretty sure the 4wd and 2wd use the same calipers, the only problem here is the offset. I wish i would have though ahead and tested it all before i bolted all my **** together, oh well, not my problem as i have a 2wd. haha

The logical train of thought is that he wants them for his truck, but don't worry Shane I am just researching right now. I have an 03 now with the bigger rotors so I need to figure out if I can get a set of brackets to work.

17x7.5 expo wheels ( they match the ones on my girls explorer lol) they will soon be wrapped in some 285/70/17 KM2s or MTRs and eventually cobra brakes if I can make it work.

They actually fit nicely with out them, I tried the ones from the expo on and they sit right where the stock ranger wheels do, and there are worse things then having to pick up a set of wheelspacers. the only thing I am woried about is having less tire to rub on rocks and roots

Aren't the bigger 4x4 brakes a 12inch diameter?? If so, that'd be tough for the caliper spacer....and it'd only be worth it if you did performance pads and high grade rotor.

Ya I want to see if I can find drawings of the knuckles and caliper mounts and see what I can do. I may plate the knuckles and redrill the holes for the biger calipers.
